Lost the baby

Latice • Gave birth to my rainbow 🌈 after 5 miscarriages. Blessed everyday I wake up and get to look into my little girls eyes.
I went to the hospital this morning for spotting. I was 6 weeks 1 day today but ultrasound only saw a sac that was about 5 weeks they couldn't tell if there was a baby. My Hcg level was only 481. This is my 4th miscarriage. Feeling really heartbroken right now.
